Large-scale properties of passive scalar advection
arXiv:chao-dyn/9901027 · doi:10.1063/1.870089
Abstract
We consider statistics of the passive scalar on distances much larger than the pumping scale. Such statistics is determined by statistics of Lagrangian contraction that is by probabilities of initially distant fluid particles to come close. At the Batchelor limit of spatially smooth velocity, the breakdown of scale invariance is established for scalar statistics.
